Turn a Popcorn Maker into an Arduino controlled Coffee Roaster

This video shows how I took a Presto Poplite Hot Air Popper popcorn maker (https://amzn.to/3k9kWTZ), and added a Relay to toggle the heat, a dedicated power supply for the fan, and a thermocouple to tell me what the temperature really is. I controlled the heater based on the thermocouple output using an Arduino Uno.

This video is just a summary! For detailed instructions on how I built this, checkout my walk-through which shares the Arduino Sketch, annotated photos, and more reference shots:

Here are the roasters I mentioned - I have no affiliation too, just want to plug some good Canadian roasters!
